System ID (anonymized)

The transfer of this data is used to optimize com-

munication between the vehicle and the mobile

phone.

To do this, and to assign several vehicles to the

mobile phone, a vehicle identier is randomly gen-

erated.

This has no connection to the vehicle identica-

tion number (VIN) and is deleted when the multi-

media system is reset (/ page 240).

The following driving status data is transmitted:

Transmission position engaged

Distinction between parked, standstill, rolling

and driving

Day/night mode of the driver's display

Drive type

The transfer of this data is used to alter how con-

tent is displayed to correspond to the driving sit-

uation.

The following position data is transmitted:

Coordinates

speed

Compass direction

Acceleration direction

The mobile phone uses this data to improve the

accuracy of navigation, for example, when driving

Mercedes-Benz emergency call system

Information on the Mercedes-Benz emergency

call system

Your vehicle is equipped with the Mercedes-Benz

emergency call system (“eCall”). This feature can

help save lives in the event of an accident. eCall

in no way replaces assistance provided from dial-

ing 911.

Mercedes-Benz eCall only functions in areas

where mobile phone coverage is available from

the wireless service providers. Insucient net-

work coverage from the wireless service providers

may result in an emergency call not being trans-

mitted.

eCall is a standard feature in your Mercedes-Benz

vehicle. In order to function as intended, the sys-

tem relies on the transmission of data detailed in

the Transmitted Data section that follows.

To disable eCall, a customer must visit an author-

ized Mercedes-Benz Service department to deac-

tivate the vehicle’s communication module.

Deactivation of this module prevents the activa-

tion of any and all Mercedes me connect serv-

ices. Aer the deactivation of eCall, automatic

emergency call and manual emergency call will

not be available.

The vehicle must be switched on before an auto-

matic emergency call can be made.

eCall is activated at the factory.

262

MBUX multimedia system

eCall can be deactivated by an authorized

Mercedes-Benz dealer. Please note that in the

event ownership of the vehicle is transferred

to another owner in its deactivated state,

eCall will remain deactivated unless the new

owner visits an authorized Mercedes-Benz

dealership to reactivate the system.

Overview of the Mercedes-Benz emergency call

system

eCall can help to reduce the time between an

accident and the arrival of emergency services at

the site of the accident. It helps locate an acci-

dent site in places that are dicult to access.

However, even if a vehicle is equipped with eCall,

this does not mean the system is ON. As such,

eCall does not replace dialing 911 in the event of

an accident.

An emergency call can be made automatically or

manually.

Only make emergency calls if you or others are in

need of rescue. Do not make an emergency call in

the event of a breakdown or a similar situation.
